“净水器中加入的阻垢剂会引起骨质疏松” 系谣言 选净水器要注意这几点

Core Viewpoint - Recent discussions on social media suggest that some water purifiers add phosphate-based scale inhibitors to prevent scaling, which may lead to osteoporosis if consumed long-term. Experts clarify that this claim is misleading and lacks scientific basis [1][5]. Group 1: Public Concerns and Misunderstandings - Many users express concerns about the cleanliness of their water purifiers due to social media posts linking phosphate presence to health issues like osteoporosis and high blood pressure [1][2]. - Users are confused by conflicting information regarding whether water purifiers should be entirely free of additives, leading to uncertainty about what to trust [2][3]. Group 2: Functionality and Safety of Water Purifiers - Water purifiers are designed to remove impurities and contaminants to enhance drinking water quality. They come in various types, with reverse osmosis being the most effective [4]. - The addition of scale inhibitors, which are often phosphate-based, is necessary to prevent clogging of the filtration membranes. The amount used is minimal, with studies indicating only 6 to 8 grams needed for processing over 20 tons of water [4][5]. Group 3: Expert Opinions on Phosphate and Health - Experts assert that the claim linking scale inhibitors to osteoporosis is based on a misunderstanding of dosage and context. Phosphates are common in food and are essential for human health [5][6]. - The risk of osteoporosis from phosphate consumption through water purifiers is negligible, as healthy kidneys effectively excrete excess phosphates [6]. Group 4: Recommendations for Purchasing Water Purifiers - It is advised to choose products from reputable manufacturers and ensure they have the necessary health permits. The use of scale inhibitors should be evaluated based on water quality [7]. - Regular maintenance of water purifiers, including timely filter replacements, is crucial to avoid contamination and ensure optimal performance [7].
